Welcome to the Cohere AI Node.js SDK.

This package provides functionality developed to simplify interfacing with the cohere.ai natural language API. This SDK provides support for both TypeScript and JavaScript Node.js projects. For a full description of the API please visit the Cohere Docs.

Installation

Install the package as a dependency.

npm install cohere-ai

Usage

Import the library to your node.js project.

const cohere = require("cohere-ai");

Initialize the library using the latest version of the API.

cohere.init("YOUR_API_KEY");

Call the endpoint function you'd like to hit to interact with the Cohere API.

cohere.generate("MODEL_NAME", config);

Endpoints

For a full breakdown of endpoints and their config objects please consult the Cohere Docs.

| Cohere Endpoint | Function | | ---------------- | ----------------------- | | /generate | cohere.generate() | | /embed | cohere.embed() | | /classify | cohere.classify() | | /tokenize | cohere.tokenize() | | /detokenize | cohere.detokenize() | | /summarize | cohere.summarize() | | /detect-language | cohere.detectLanguage() |

Models

To view an up to date list of available models please consult the Cohere CLI. To get started try out large.

Responses

All of the endpoint functions will return a response structure. For a detailed breakdown of the response body visit the Cohere Docs.

{
  statusCode: STATUS,
  body: RESPONSE_OBJ
}

Code Examples:

(async () => {
  cohere.init(process.env.COHERE_API_KEY);

  // Hit the `generate` endpoint on the `large` model
  const generateResponse = await cohere.generate({
    model: "large",
    prompt: "Once upon a time in a magical land called",
    max_tokens: 50,
    temperature: 1,
  });

  /*
  {
    statusCode: 200,
    body: {
      text: "Eldorado, the anointed monarchs of the ancient world and the ruling family were divided into three kingdoms, each of which was ruled by an individual leader."
    }
  }
  */
})();

Example error response:

// error response from cohere.generate() where api key was not previously provided.
{
  statusCode: 403,
  body: {
    message: "Whoops! You need to provide an API key before making requests. Try cohere.init(YOUR_KEY)."
  }
}

TypeScript support

Import the package as a class.

import cohere = require("cohere-ai");

Require the cohere package as usual, and the ./index.d.ts file will be imported by typescript automatically.
